[Q] Cant flash ROMS from stock 4.2

I have newly acquired a samsung s4 active with 4.2 stock. I couldn't OTA upgrade or manually (keeps failing halfway through), couldn't flash 4.4 ROM through recovery, and couldn't do backups through ROM manager and recovery 3.0+
At this point i'm not sure what i should do. i'd like to set my phone up and forget it.. but nothing is really going easy for me. is this because of the s4 active recovery? why is it so hard to change that darn 4.2 stock rom?

It depends on which version of the phone you have. If you have the i9295, then it really shouldn't be that hard to do what you are asking about. If you have the i537 then you can't really do anything you're asking about because it has a locked bootloader. If you have the i537 you need to check out SafeStrap.

i believe i do have the i537. is there a thread i can check out to help with getting started on custom recovery roms etc?

The i537 has a locked bootloader which means you cannot install a custom recovery or any other kernel. Your only option is to use SafeStrap along with 4.2.2 TouchWiz-based ROMs. Read more about SafeStrap here and a list ROMs that will work with SafeStrap here.
Because of the locked bootloader you will not be able to use CyanogenMod, any CM-based ROM, or any AOSP-based ROM. The only ROM I like using that is different than the stock ROM is the 4.2.2 GPe. Do some reading before you try SafeStrap, otherwise you could brick your phone pretty easily.

[Q] At&t Note 3 bootloop/flash stock help

hi everyone, im a newbie and im having a little trouble understanding and fixing my phone.
so ill start at the beginning, i bought a note 3 from at&t N900A and then moved out of the US (after contract expired and i sim unlocked with the code they gave me.)
I could not connect to at&t servers from outside US to OTA update. (i dont remember if i was mj5 or mi9)
So i learned about rooting while trying to update and decided to use kingo root app and got root access
then i installed safestrap 3.71 for a custom recovery, then i backed up my stock rom and made a new rom slot. Then i resorted my stock rom to rom slot 1.
this is my mistake: i flashed the knoxraid rom from here
http://galaxynote3root.com/att-galaxy-note-3-roms/knoxraid-kitkat-rom-for-att-galaxy-note-3/
however i forgot to do the data/factory wipe. To make matters worse i realized this and pulled the battery out after about 20 seconds (the download bar was about 10% complete)
when i put the battery back in the phone went straight to recovery (recovery and download mode were the only ones working)
i started panicking as this was my first time rooting/installing roms and tried to find a solution
i found one and used this:
http://www.droidviews.com/how-to-unbrick-att-galaxy-note-3-sm-n900a/
i flashed all the files correctly and odin got to about 95% and the said FAIL
i panicked again when i turned my phone on and it went to an error screen saying firmware upgrade incountered an issue etc.
before i harm my device further i would like to know what to do (i can still get to download mode)
odin mode say it is A2 so i belive that is mj5
i want to know: should i reflash stock mj5, and if so please provide link
should i do this: http://forum.xda-developers.com/showpost.php?p=48243768&postcount=1
should i use the N900AUCUBMI9_OneClickBin.exe
or should i flash nc2 files found here: http://forum.xda-developers.com/note-3-att/general/n900aucucnc2-odin-files-t2838117
will the nc2 kitkat brick my device? keep in mind it is running A2 which im sure is mj5
Thank you everyone in advance

NC2 won't brick your device, but it'll upgrade your bootloader to A3 which will prevent you from ever downgrading back to MJ5 (not that you'd want to anyway). I'd just go with NC2 since it's rootable with TowelRoot anyway. Also, in your case I'd recommend using the 4-file method rather than the 1-file method since it's an upgrade from 4.3 rather than just a restore to stock 4.4.2.

You might want to consider adding the Pit file too to repartition your phone just in case anything got messed up in the failed odin flash that would definitely clean everything up. It might be overkill but I don't think it would hurt to do since you're doing a factory reset with the 4-file install anyway

[Q] AT&T Galaxy S5 upgrade Help!!!!

Forgive me I am a noob. I recently rooted my AT&T S5 cause was waiting for the 5.0 update to come out. I decided to go back to stock and upgrade and removed the root all except the bootloader still appears with custom when starting phone and is only trace of root is all can seem to find but is keeping me from installing new 5.0 as it gets to 28% and restarts says unable to install instillation interrupted. How can I replace bootloader with stock one and where may I find one? Any and all help appreciated. I am running 4.4.4 android and is a SM-G900 AT&T S5 with kernel G900AUCU2AOA1.

Install Samsung Kies on your PC/MAC, and try flashing a new firmware with Kies. Follow the on screen instructions

I have tried that and tell me that my software is up to date have also tried a few different stock roms which were supposed to work with my phone with Odin and they all fail.

Flash the file in this thread.

Thank you very much for the help and sorry has taken so long to get back and let you know it worked great. Thank you so much

(Q) I527 stuck in Download

(RESOLVED)
Alright so in order to not bore you all, ill get to the point. I messed up trying to do impossible things with my I537 because I didn't read any forums before trying... stupid I know. That being said I now have a "soft bricked" phone stuck in download mode. I have been looking around (I assume not hard enough) for the right file to flash with ODIN to get me back up and running so I can actually do my research this time before playing with different stock roms.
Can anyone point me in the right direction to get the right files to unbrick this thing?

First things first: this forum is for the SGH-I537 AT&T Galaxy S4 Active, not the I527 Galaxy Mega. I just want to make sure you have the right device. If you have the Mega (I527), you want this forum, and ignore the rest of this post.
If you do in fact have the Galaxy S4 Active (I537), then check out this thread, it has all the official firmware files that have been released for this device. I would recommend using the firmware files for NE3 (KitKat) to flash in Odin. The NE3 build is the easiest to root, and you can always use the keep-root method to upgrade to lollipop if you so desire.

Oh yes sorry that was a mistype. I did indeed mean to type I537. Ok Ill give this a shot and update on how it goes.

Ok so Im currently downloading the Full Odin package, but I have already rooted the phone with towelroot. Is that going to be an issue?

Nah it won't be a problem. Flashing firmware files with Odin will unroot your phone (it resets everything to original factory settings). You can always reroot with towel root again

Ok new problem though, I was able to get everything flashed through ODIN, it restarts; then I get the Samsung boot screen, att boot screen and then it just goes black. I put it back into download mode and tried to re-flash it a couple times but it keeps doing the same thing. Thoughts? This Is the section I got the file from;
I537UCUCNE3 (4.4.2) Released 2014-06-06 - OFFICIAL

Issue has been solved, I just had a battery issue but after changing that and letting the phone charge up it started up great. Thanks for all your help "thisisapoorusernamechoice"

Failure to install TWRP ROM [Samsung Galaxy S4 Active]

So I have been trying to install a custom recovery on my rooted phone, I am on 5.0.1 or 5.1.1 not sure at the exact moment but when I go to install TWRP Odin mode I believe it is, is stopping me from continuing so the device is just sitting at "Downloading... Please do not turn off the target". I attempted multiple different flash APKs (Because I don't have a computer). I did see another post with someone who has the same problem (not sure if he used a PC) but this is very annoying. Can someone please assist me?
I am making sure my device is rooted, I have the proper version for my device I just need to use this to install Xposed installer on my phone, but again, no PC access..

Based on a post you made in one of the other threads it sounds like you have the i537 (AT&T version of the phone). If this is the case you have a locked bootloader, meaning you cannot flash any custom recovery. You're only option is to use FlashFire to flash things.
If I misinterpreted what you said and you do indeed have the i9295 (international version of the phone), you should be able to put a custom recovery on your phone.
Based on what you said above, you are putting the phone in download mode where you can use Odin to flash things to your phone. Odin is a PC program and you can only use the phone in download mode in conjunction with a computer. You need to put your phone in recovery mode in order to be able to flash things without a computer. It sounds like you need to do some more reading about what you're attempting to do and how your phone works because you are starting to mess with some low-level programming on your phone and you could permanently brick it.

This is true, I have the AT&T variant. My friend sold me this for real cheap so brick in it isn't the worst thing. I did state I cannot use a PC as I do not have one. I also don't believe I can put my phone into recovery mode, or at least I don't know how. I tried [HOME+PWR+VolDown] and I believe it tried to install the recovery. So, maybe I am missing something there is a lot to read. Do I need a computer to do this or can I found it without?
Could you please maybe private message me or leave it here, a step tutorial on how to put this phone into recovery and install the a custom ROM. (I know how to use flashify already) the only issue is the locked bootloader. Thanks for the information. I do not have the international phone. Just AT&T. Not unlocked.

You cannot install a custom recovery or flash anything through the recovery menu because AT&T locked the bootloader. The only ROM that exists right now for the i537 is the Slick As Hell ROM in the development section.
As far as learning more, check the stickies it's always a good place to start.
